A novel series of 2-amino-5-spiro substituted oxazolin-4-ones and intermediates for making said compounds. These compounds are prepared by first converting the appropriately substituted cycloketone to the corresponding cyclocyanohydrin; converting this compounds to the corresponding hydroxy acid; esterifying the hydroxy acid, and finally cyclizing the hydroester to form the 2-amino-5-spiro substituted oxazolin-4-one. These compounds exhibit central nervous system activity and are active as either stimulants or depressants, and some are useful as performance enhancers.
